What is a chart recording instrument?
A chart recorder is an instrument used to record various process and electrical signals. The paper is passed under a pen and the pen is deflected in proportion to the signal. The result is a graph or chart of the data.
How does strip chart recorder work?
Strip chart recorders consist of a roll or strip of paper that passes linearly beneath one or more pens. As the signal changes, each pen’s deflection records the process being measured in the form of a chart.
What is a circular chart recorder?
Circular chart recorders are data acquisition tools that archive data points onto a uniformly rotating circular chart over a timed interval in proportion to the signal received. The charts usually rotate over standard time periods (e.g. 24 hours, one week, one month, etc.)
What is mechanical chart recorder?
A chart recorder is an electromechanical device that records an electrical or mechanical input trend onto a piece of paper (the chart). Chart recorders may record several inputs using different color pens and may record onto strip charts or circular charts.
What is a Bristol recorder?
This is a Record Store Day 2018 item. Back in 1979 The Bristol Recorder was one of Bristol’s most unusual musical entities and in 2018 The Bristol Recorder Volume 4 aims to restore a vinyl voice for Bristol and its music. The Recorder combines a sixteen page magazine with an LP record.
What is XT recorder?
A strip chart recorder is used to record a signal level over time. The original recorders used an ink pen that drew the input signal amplitude onto a roll of moving chart paper. A basic XT recorder had a single input (X) and plotted the input signal amplitude over time (T).
Which is the basic elements of strip chart recorder?
The basic element of a Strip Chart Recorder Working Principle consists of a pen (stylus) used for making marks on a movable paper, a pen (stylus) driving system, a vertically moving long roll of chart paper and chart paper drive mechanism and a chart speed selector switch, (as shown in Fig.
What is a Barton meter?
The Barton® Model 202E single DP Flow Recorders measure and record system operation parameters including gas and liquid flow rate, liquid level in a vessel, and other system variables that can be measured by differential pressure and static pressure methods.
What is XY recorder?
By the term X-Y recorder is meant an instrument that is capable of plotting any two variables against each other, rather than against time. This requires that the recorder be able to plot multiple-valued as well as single-valued curves.
How do you distinguish XY recorder from a XT or a YT recorder?
An XY strip recorder could plot the X input variable versus time (XT), the Y input variable versus time (YT) or sometimes the X variable versus the Y variable (XY). They’re still in use but are getting squeezed out of existence by units that use LCD displays and electronic memory.
Which recorder is known as null recorder?
Null type instrument: An instrument in which zero or null indication determines the magnitude of measured quantity, such type of instrument is called a null type instrument. It uses a null detector which indicating the null condition when the measured quantity and the opposite quantity are same.
What is the function of stylus in the recorder?
Marking with ink filled stylus is most commonly employed as ordinary paper can be used. The stylus is filled with ink by gravity or capillary actions. The stylus moves over the paper with pre printed scales, and traces the variation of the input signal.
